## Affected

- Unknown ElementsKit Elementor Addons: fixed in 3.10.01

## Description

The ElementsKit Elementor Addons WordPress plugin before 3.10.01 does not sanitize or escape certain megamenu menu-item settings before storing them and outputting them on the front end, and does not require the unfiltered_html capability to save them, allowing users with administrative capabilities to store malicious JavaScript; on a multisite network this lets a non-super subsite Administrator, who is denied unfiltered_html, plant a stored Cross-Site Scripting payload that executes in the sessions of the network Super Admin and site visitors.
